My best friend in high school is Lan. Lan sits next to me in class, eats with me at break time, and hangs out with me after school. She has long and beautiful hair; my mother always says that I need to pay more attention to my hair so it can be pretty as hers. I am good at English while Lan is excellent in Math, therefore we can help each other every time one of us has trouble in understanding those subjects. Besides our study, Lan is always by my side whenever I feel upset. I tell her everything, and only her can know my true feelings. We have been best friends since our young age, and I will keep this friendship forever.

I have a bestfiend and also a neighborhood whoes name is Tuan. His age is the same as mine but he looks older than me. Because he’s very tall and thin, everybody calls him “a palm”. Tuan has a short curly hair and beautiful chestnut brown eyes that appeal of many girls. He is a person of very few words that makes him to be a good listener. Anyone, who has ever contacted with Tuan, thinks about him as a glacial boy. In fact he’s really warm and nice. He’s willing to help people whenever possible. When I was in secondary school, I found Math was very difficult to understand but Tuan solved the Math problems so fast. He spent all seven nights of weeks to help me in Math while he could go out to relax. Tuan was a good all-rounder exception English. Most of the teachers in school and parents highly appreaciated his talent. Only a month ago, he received two full scholarships from America Government to study oversea but he has not yet decided whether he should go or not. Although he has not spent much time to take part in sport activities, he is a well football player. We were in Ha Noi Young Football Team when we were in grade 10. Everything seems perfect to my bestfriend but he’s very modest and always talks to himself to give more effort. I’m proud of Tuan and pray for the good things beside him forever.

Ta có:\(x+30\%\cdot x=-1,3\)
<=> \(x+0,3\cdot x=-1,3\)
<=> \(x\cdot\left(1+0,3\right)=-1,3\)
<=> \(x\cdot1,3=-1,3\)
<=> \(x=-1,3:1,3\)
<=> \(x=-1\)
Vậy: \(x=-1\)
